Fig. 8. Comparison between the stress waves [MPa] propagating from the epicenter after 0.04ms of interaction time (end of load history).

Fig. 9. Comparison between the maximum principal stress values predicted by the simulations at halfway through the diagonal bisection of the plate (88.4mm from epicenter). Fluid structure interaction (red), uniform pressure distribution on a circular area with 1.5 times the radius of the bullet (green), uniform pressure distribution on a circular area with 2.0 times the radius of the bullet (blue).

Fig. 10. Comparison between the maximum principal stress values predicted by the simulations at halfway through the orthogonal bisection of the plate (62.5mm from epicenter). Fluid structure interaction (red), uniform pressure distribution on a circular area with 1.5 times the radius of the bullet (green), uniform pressure distribution on a circular area with 2.0 times the radius of the bullet (blue).
